(Cl. 20G-16) (Granted under the act of March 3, 1883, as amended April30, 1928; 370 0. G. 757) 2 Claims.

The invention described herein may be manufactured and used by or forthe Government for governmental purposes without the payment of anyroyalty thereon.

This invention relates to a support whereby the barrel of a firearm maybe secured within a tubular container and axially positioned therein bysimple adjustment of the support.

In the storage of cal. .50 machine guns, particularly of the aircrafttype, in tubular metallic containers, it has been found that thesupporting means for positioning the barrel or barrel jacket within thetubular container is far from satisfactory due primarily to the bentcondition of the tube and to other factors. Former jacket supportingdevices did not permit of any adjustment whereby the barrel and barreljacket could be readily centralized within the tube.

Accordingly it is an object of this invention to provide a supportingdevice for axial a firearm container which surrounds the barrel orbarrel jacket of a firearm, and permits lateral adjustment for alignmentof the barrel or barrel jacket within a tubular container.

Another object of this invention is to provide a firearm supportingdevice for securing the jacket of the firearm within a tubular containerwhereby such support may be quickly and conveniently locked to the wallof the container.

A particular object of this invention is to provide an adjustablefirearm support for the U. S. machine gun, cal. .50 M2 aircraft gunrforstorage in a tubular metallic container.

The specific nature of the invention as well as other objects andadvantages thereof will clearly appear from a description of a preferredembodiment as shown in the accompanying drawings in which:

Fig. 1 is a plan view of the adjustable firearm support.

Fig. 2 is a fragmentary longitudinal sectional view of a firearmcontainer showing the adjustable :firearm support supporting the barreljacket of a rearm within the container.

In Fig. 2 there is shown in assembled relation a firearm supportembodying this invention. Such support essentially comprises a disk-likeplate IIJ and a ring II secured to disk-like plate I by a plurality ofscrews I2. The outer edges of plate I0 and ring II are iiared as shownin Fig. 2 to form a substantially V-shaped iiange I3 when the ring andplate are joined as shown in such iigure. A split ring I4 as shown at I9is placed within the V-shaped flange I3 and such ringis semi-cylindricalin cross section as shown in Fis.

2 so that the flanges of plate I0 and ring II contact such ringsubstantially tangentially. An axial hole I5 is formed in plate I0 andan integral hub I6 is formed about hole I5. Hub I6 snugly engages ajacket II of a machine gun (not shown).

The assembled firearm support may then be inserted within a cylindricalcontainer I8 shown in Fig. 2. rIfhe customary procedure however is tohave thefirearm (not shown) substantially in place in container I8whereupon the rearm support is slid over jacket I'I of such iirearm.When the desired vertical location of the firearm support is attained,the jacket is laterally positioned within container I8 by tightening andloosening adjusting screws I2 the amount necessary to align such jacketsubstantially axially with respect to the container I8. When jacket I1is properly located, screws I2 are tightened whereupon split ring I4 isforced outwardly to bear tightly against the inner wall of container I8. Thus the firearm support is locked in place.

To those skilled in the art it is herein apparent that an improvedfirearm support is provided which will permit limited lateral adjustmentof the barrel jacket of the firearm within the container while at thesame time allowing the support to be locked securely in place by asimple yet positive friction device whereby the support is readily andsecurely positioned within the container so that any possible shiftingof the flrearm is substantially eliminated.

I claim:

1. In a tubular container for a iirearm having a barrel jacket, asupport member insertable in the container, said support membercomprising a disk having a flared rim. said disk having an opening to'accept the barrel jacket, a Iring mounted on said disk in spacedrelationship, said ring having a ared rim adjacent said fiared rim ofsaid disk, each of said iiared rims defining a side of a substantiallyV-shaped groove, a split ring in said V-shaped groove, said split ringhaving a substantially semi-cylindrical cross-section so arranged as tobear substantially tangential on said iiared rims, and screw means forvariably spacing said ring from said disk whereby said split ring may bepositioned to align the barrel jacket within the container and toaxially secure said support therein by expansion of said split ring.
